This invention relates in general to locks, and more particularly to the type commonly known as coin controlled locks adapted for use on parcel lockers, cabinets, lockers, and

the like where the deposit of a coin is desiritble as a prerequisite to manipulation of the 00k; V

The lock of my present invention is designed to remain normally in unlocked position, permitting access to the-locker or other container which the lock controls,-the lock being automatically retained in unlocked positi'on with the key so disposed therein that it cannot be removed until the lock has-been moved to locked position.

When use of the locker is desired, the user, after the articles to be protected have been deposited in the locker, inserts a coin through a slot in the lock case, which coin, when the key is then turned, serves as a medium to release the look from its normally unlocked position and actsas an operating link or member to move the bolt into locked position so that the key may be withdrawn and retained by the user as his check until such time as he desires to open the locker, whereupon he inserts the key and unlocks the lock in the usual manner.

One of the primary purposes of'my present invention is to provide a lock of the general character indicated, which will be 6 X-. tremely simple in its construction, and will embody a minimum number of parts so that it can be economically manufactured, and one which will be positive and reliable in operation and not apt to get out of order or be subject to breakage or the necessity of repairs. r

Another object of my invention is to provide a lock in which complicated locking and control mechanism for normally holding thelock in unlockedposition will be eliminated. My present: invention comprising, in

addition to the locking bolt, but one moving part which is carried directly by the key cylinder and cooperates with the bolt ltsclf to retain the lock in unlocked position until the bolt and this member are disengaged by.

any well known or preferred.construction,

' the action of a coin deposited in the lock.

A further feature of my'invent-ion resides in the fact-thatthe :two moving partsin ay be (cast or otherwise manufactured at very lowcost, and the part which isfcarried :by .the

key-cylinder "capable of being attached-"to a cylinder of any standard. .or' preferredv type, i may he "purchaseril 1n the open Serial No. 563,770.

market, thereby obviating the manufacture of a special type of lock and key.

Another feature of the lock resides in its posit-iveness' of operation, the construction being such that the locking bolt is positively moved into locked position through the intermediary of a coin, its lock action notbeing dependent upon springs or other mechanism liable to get out of order, but on the contrary,.being positive in character, thus ensuring its locking movement, reliability of the lock and obviating dangers of loss of articles from the locker resulting from failure of a lock to operate.

Other objects and advantages of this invention should be readily appreciated as the same becomes better understood by reference to the following description when consid ered in connection with the accompanying drawings.

I Referring to the drawings Fig. .1 is a rear elevation of a lock embodying my invention;

Fig. 2 is a similar view showing the bolt in locked position;

Fig. 3 is a sectional view on the line 33 of Fig. 1;

Fig. at is a detail perspective view of the operating member carried by the key cylby a guide 9 screwed to the case and embracing the'bolt at a point remote from the flange 7. VVith-in the casing 5, and substantially in alignment with the elongated portion of the bolt .8, there is'rotatably mounted a lock cylind'er case or housing 11, which may be of secured to the case-by screws or' otherwise and adapted to: rotatably receive the usualtumblers (not shown) and the key cylinder 13 cooperating therewith... I

Upon the outer' end ofithisgcylinder, which in the present instance has a centrally projecting; portion l4; to; add strengthto-thestructure, there is secured an operating mem ber, illustrated in Fig. 4, comprising a camt other means, and isadapted to partake of the movements of the cylinder which are imparted to it through the instrumentahty of the key 19 in the'usual manner.

Above the cylinder housing, the case .6 is provided with a slot 21 through whicha coin may be introduced, the coin belng guided into the receivin slot 22 of the coin receiver 17 by a channe r-shaped coin gulde 23 disposed upon the inner facing of the casing in alignment with the slot.

The coinreceiver is normally retained in alignment with the lower end of the coin guide to receive a coin inserted therein, by a tractile spring 24 attached at one end to the casing 5 and at its opposite end to the cam member 15, as shown in Figs. 1 and 3.

The key cylinder-is normally retainedin unlocked position and held against locking movement by the engagement of-a lug or boss 24 formed=on the outer face of the member and adapted to engage with a lug'or boss 25 formed on the head ,28 of the locking bolt 8 and disposed, when the lock is in unlocked position, in the path of travel of the lug 24, whereby rotative movement of the key cylinder in a counter-clockwise, direction, viewing Fig. 1, is" limited. A second lug 26 formed on the inner face of the member 15 engages with the tumbler housing 27 of the cylinder case, thereby limitingthe movement of the key cylinder in a clockwise direction, viewing Fig. 1, to substantially the position therein shown, wherein the coin receiver is disposed in lVhen the parts are in this position, the cylinder tumblers prevent withdrawal of the key from the cylinder so that the key is there fore locked in the cylinder against re moval.

The head 28 of the locking bolt 8 is ex tended upwardly to dispose its upper 8X1 tremity inproximity to a coin 29 when p0- sitioned in the coin receiver, as shown'in Fig. 1. .Upon initial rotation of the key cylinder, the coin engaging the opposed end 1 of this headtorces the head and its bolt 8 to the left, viewing Fig. 1, to thereby move the lug 25 outof the path of travel of the lug 24, thus permitting continued rotation of the key cylinder until the locking boltis fully projected into:locking position, as; shown in "Fig, 2. Further movement of the cylinder is then arrested by a lug ,31

, ting out of mounted substantially at the opposite side of the member '15 from the lug 24. When the parts are in this locked position, as illustrated in Fig. 2, the tumblers of the key cylinder and cylinder casing are disposed in-alignment so as to permit withdrawal of the key 19. After the coin has passed the lower edge ofthe bolt head, the. bolt is held against retraction by the perimeter ofthe cam member 15 which engagesa flange 32 formed on the bolt head. The coin 29, after the locking movement of the bolt has been effectechwill drop by gravity from the receiver. 17 through. an opening 33in the case 6.into a chutetnot shown) by which it is conducted to a coin collecting recep tacle.

The lock will remain in locked position to which it has been moved until the user re-inserts the key 19 in the cylinder, whereupon the key is turned in theoppositedt rection to restore the cylinder to thenormallyunlocked position shown in Fig-.1, the bolt being retracted from projected. position by a tractile spring34. During the return movement, .the outer edge of the coin. receiver 17. will limit the retractive movement of the bolt softhat the lug 24 will engage the outer end of the lug 25,;

andas soon as lug 24 has passed above lug 25, the bolt will be .ifully retracted to dispose lug 25in the path of lug 24, thereby locking the device against locking "movement until the coin has again been deposited in the slot.- A coin, when deposited, serves as an operating instrumentality to project the bolt and clear the lug 25. from the path otlug 24, so that complete locking movement of theparts may be effected. In the absence of a .coin the engagement of these lugs will preclude lockingfmovements of the apparatus. Y

It will be apparent from the foregoing that I have provided a coin controlled lock comprising merely-the locking bolt and a member carried by the key cylinder and adapted to receive a coin. Then in unlocked position the bolt holds the cylinder against locking movement, and when in' locked position the member carried by the cylinder holds the bolt/against. locking movement. The device is extremely simple in construction and operation and reliable and durable in use, and since it consists of a minimum number of parts dangerv of get order is practically eliminated.
